I am interested at getting visa to visit India. I can realize that is possible to get visa with a validity of 3 or 6 months, but I don't know how many days in a row I can stay at the country with a single entry. For example, if I get visa with validity of 6 months, it is possible to stay during the whole period in india? Or is it neccesary to leave the country and make a new entry after some period of days?
